Create a superior driving experience
In recent years, the requirement of automobile equipment operation
has been increasing.Our lead-free bearing material, with enhanced
performance, can meet the most stringent performance requirements,
better than ball bearings (limited space and weight, high load and
swing movement may cause damage).
Bearing has many advantages, creating superior driving performance:
· long service life, reliable and smooth operation
· high wear resistance
· low friction coefficient, low loosening torque and no stick-slip
· compatible with many standard oils and lubricants
· high precision and stable size

customer-specific bearing designs to provide comprehensive customer
Metal Polymer Composites Plain Bearing
Improve quality and environmental standards
Our environmentally friendly, lead-free bearings reduce
installation, operation and maintenance costs.
Double Mass Flywheel (DMFW) is a new structure applied in the
automotive power transmission system in the late 1980s, which can
effectively isolate the torsional vibration of the engine
crankshaft and is conducive to improving the performance of the

VSB-10 Self-Lubricating Multilayer Composite Bushing
Bushing material suitable for lubricated applications
self-lubricating bushings offer very good wear and low friction
performance over a wide range of loads, speeds and temperatures in
dry running conditions
Anti-friction bearing suitable for linear, oscillating and rotating
Material is designed to operate without supplemental lubrication
and will perform excellent when lubrication is present. Low
friction, low wear rate, good sliding characteristics and very low
absorption are a few of the features of this material. VSB-10
bushings will support rotary, linear and oscillating motion.
1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact
surface for the rotating shaft. Minute partides of the PTFE layer
and the sintered bronze material combine to create a solid
lubricant film, which coats the shaft.
2. Sintered bronze powder thickness 0.20*0.35mm,A special
composition of powdered copper is thermally fused to the steel
backing. This contact layer acts as an anchor for the PTFE layer
and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel backing. Setting the foundation of the
bushings, the steel back provides exceptional stability, load
carrying and heat dissipation characteristics.

The main factors affecting the life of self - lubricating bearings
1: load P: the greater the load, the shorter the service life of
the bearing;Under no circumstances shall the maximum load exceed
the theoretical maximum allowable load.
2: speed V: the higher the speed, the shorter the service life of
the bearing;Under no circumstances shall the maximum sliding speed
exceed the theoretical maximum allowable value.
3: PV value: the working life of the bearing depends on the PV
value, that is, the product of the actual load P and the sliding
speed V. The smaller PV value is, the longer the bearing life is.
4: temperature: the life of the bearing also depends on the
temperature when the bearing is in use, the higher the temperature,
the shorter the life of the bearing, so in the design and selection
should try to consider the heat dissipation characteristics of the
5: surface roughness of the grinding parts: alloy steel or hard
chromium plated shaft is used for the grinding parts. When the
surface roughness Ra=0.4-0.63, the service life of the bearing can
be significantly improved.
6: other factors such as bearing design, lubrication conditions,
viiplus products are widely used in all industrial fields

tool industry, plastics machinery industry, lifting and handling
machinery, port machinery, office, fitness machinery, textile
machinery, food packaging, filling machinery, chemical machinery,
